The 22 drivers have their say on the opening day of action at the legendary Monza circuit.
McLaren
Jenson Button: "It's always fun to drive around such a fast circuit. You don't really feel the speed, it's more about getting used to the extremely low downforce set-up that we run around here.
"Early on in FP1, my DRS stuck open - we use a completely different DRS system for Monza because it's a low-downforce circuit. The mechanism stuck open in the shroud - which was a mistake - but it was quickly fixed by the guys in the garage.
"Despite that problem, FP1 was actually better for us than FP2, when we weren't quite as competitive. Nevertheless, there's a little bit more pace in the car that I hope we'll be able to extract - so it would be nice to get through to Q3.
"We changed quite a bit between the sessions today, and we think we know what works and what doesn't. It was a positive day in terms of understanding the car, actually.
"There are a lot of cars only narrowly ahead of us - it's extremely close out there. So we're going to work as hard as we can overnight. Having said that, we know that the race will be more important than qualifying."
Sergio Perez: "We managed to complete a very positive programme during both of today's sessions.
"In fact, we got through everything on our job-list today, which is a real positive. As always at Monza, we tried varying levels of downforce - that's an important thing to get right here - but it's a very difficult decision to make around here.
"Clearly, we need to make the right call for Sunday. In fact, as Jenson says, I don't really feel that qualifying tomorrow will be quite as important as it usually is; the key for us will be to engineer ourselves a good set-up, with a good strategy, for Sunday.
"So, in actual fact, we'll spend more time thinking about Sunday, and not so much looking at tomorrow. I'm not even too focused on getting into Q3, because I know our main aim will be about how we manage everything on Sunday."
Lotus
Kimi Raikkonen: "The car felt pretty normal for me today and we're going to look at the data in order to make a decision on whether to use today's specification or the older one. It doesn't feel much different to me so it'll be a decision based on what the data says.
"Today we were a little surprised to be third fastest, but we're still quite far away from the fastest cars. There are still some areas for improvement so hopefully we can find more speed for tomorrow."
Romain Grosjean: "We had a productive day today. The timesheets showed that Kimi and I were very close, however that doesn't necessarily mean a lot. Kimi tested the new long wheelbase car and from today's work we have sent data back to the factory and we will see what the outcome is when analysis comes back.
"As drivers, our feedback on the feel of the car is also key. It is hard to precisely compare the two though; it could provide more brake stability which is what we all want here in Monza, however each driver also has their own braking style."
Mercedes
Lewis Hamilton: "The car feels pretty good here today at Monza. The balance is reasonable and we've had a pretty smooth day, better than our recent Fridays in fact. Although we're quite competitive, we're not quick enough yet and will have to work hard tonight to see where we can make some improvements. Of course we don't know what fuel loads other teams are on so we'll have to wait and see but there is a bit of work for us to do if we want to compete right at the front tomorrow."
Nico Rosberg: "As usual on Fridays, we are a bit away from the quickest times, however we learned a lot today. Almost every single lap brings important information and I think our car is good again. We need to work hard this evening to improve further though as the Red Bulls are very quick again. Generally it's a great atmosphere here at Monza; the track is absolutely fantastic and the fans are very enthusiastic. There's always a great welcome for us here."
Sauber
Nico Hulkenberg: "It was quite a challenging day. This morning was compromised a bit by a gearbox issue, which we were able to solve before the afternoon session. When doing the long runs I felt more comfortable in the car than with low fuel. We definitely have some room for improvement there. We have to look into the data and analyse what happened, because I think we can be more competitive. Otherwise, as usual, we were learning about the tyres and the set-up."
Esteban Gutierrez: "It was a very productive Friday, without any issues on the car. We were trying to find the right balance and set-up of the car in the morning. In the afternoon, we made a decision, which wasn't the best. Overall it looked positive and we have very good data to analyse so we can make the right decision about the set-up of the car tomorrow."
Force India
Paul Di Resta: "The car seems to be relatively well balanced, but we've not been able to break into the top ten yet. So we need to work away tonight to try and improve things a bit more. Making Q3 tomorrow is the big target, which is definitely achievable. The field looks quite spread out here, certainly compared to some other races, but we seem to be close to McLaren. The tyres are performing in line with our predictions and we've got plenty of data to go through tonight."
Adrian Sutil: "Monza is an unusual track so it's been quite a challenge to get on top of the car today. There's certainly a lot to look at tonight because we need to improve the car under braking and make it easier to drive as I'm lacking overall grip at the moment. For the tyres we have the data we need and the long run performance looked okay."
James Calado: "Amazing - that's the only word I can use to describe the day. It took a while to get used to the car again, but once I was familiar with everything I was able to drive consistently and set some reasonable lap times. The balance felt good and everything ran smoothly during the session. I learned a lot and hopefully got some good data for the team. I want to say a big 'thank you' to Sahara Force India for the opportunity and I'm already looking forward to getting back in the car later in the year."
Williams
Pastor Maldonado: "We completed all the plans we had today. There is a lot to look at as we are close to the limit so it's hard to find a few more tenths of a second. It is quite difficult to put a lap together as there is some inconsistency in how the car behaves through different corners, but we will see where we are tomorrow as the track is changing a lot. We weren't able to improve our time too much this afternoon so we need to work harder to make sure we are better tomorrow."
Valtteri Bottas: "It wasn't an easy day today. We had some inconsistencies in the aerodynamics during FP1 and then in FP2 we were missing quite a lot of straight-line speed on my option tyre run. We need to look at why that happened as that is why the time doesn't look so good on the board. The positive thing today was the long run as we were competitive compared to Toro Rosso and Sauber and I think we can really challenge them in the race this weekend."
Toro Rosso
Jean-Eric Vergne: "The car worked well in the morning, but we were not so competitive in the second session. On my short runs and also on the long one, I had a problem with the balance of the car, although this afternoon, that aspect was a little bit better than in the morning.
"Generally though, I suffered with a lack of grip, which I can't explain at the moment. However, I am confident we can find ways of moving forward and enjoying a competitive weekend at our home race."
Daniel Ricciardo: "Our performance was quite good this morning and we tried to improve for FP2, but unfortunately, we seem to have gone in the wrong direction. Having run only the Hard in the morning, in the afternoon, I did not set a competitive time on the Medium. I did make some mistakes and I will admit to that, but there were too many of them so we definitely need to get the car to suit me a bit better.
"At the moment, it's on a knife edge. I was happier on the long run I did this afternoon and that was the most positive aspect. Driving here at Monza is always different and this morning, on the first runs, you definitely feel that extra speed down the straight, which is a nice feeling and something I enjoy about being here."
